' vucpl-'a-BLlialalala'.4 i l To all whom it may concern,.-

Beit known that I, REUBEN C. N ELsoN, a citizenMof the. United States, residing at Healdsburg, in the 'county of Sonoma and State of California, have invented a new and useful Va or-Burner, of which .the following is a spec' cation.

This inventionv relates to apparatus in which liquid fuel is emplo ed, more particularly to devices of this c aracter in which crude oil is emplo ed as a fuel.

The device 1s esigned foruse in `connection with furnaces f various kinds. For the p .ose of illustration the device is shown app 1ed to an ordinary steam-generator furverse section on t T su pl -tank for .the fuel located at an able below the line of the same, and a eater for the liquid `fuel between the burner and. tank.

The tank is' represented at'lO with a suctionpipe 11 extending therefroml and provided a ly near The pipe 11 eads to a'cap 12, having a transverse partition 1 3 and connected, preferably by threading, to one end of a relatively lar e shelll or pipe 14. The partition 13 and t e end of the cap 12 form a comparatively broad shallow compartment 13, into which the pipe 11" opens. Connected, preferably by threading, tothe other end of the shell 14 1s another cap 15, the latter having a pipe 16 leading therefrom and constituting the feedpipe to the burner, (represented as a whole. at 17.) Within the cap 15 is a disk lplate 18, bearing against-the end of the she 14 and held in place lby a shoulder 19 within 15. A comparatively broad but shallow compartment 15 is formed between the late 18 and the end of the pipe 16 opens.

The partitions 13 and the plate 18 are pierced with numerous apertures for receivmg a plurality of tubes 20, the -tubes threaded I Specification of Letters Patent.

at the ends and supplied with clam -nuts22 ,entering the compartment13a will be heated yto a certain extent with the 'compartment 15, which is alsover the consumption'of the same amount of fue .cured within the the cap cap 15 `into whic the 22, bywhich they are secured to t e partition 13 and plate 18. A steam-pipe 23 leads into the shell 14 at one point, and an exhaustipe 24 leads therefrom at another point. t will therefore be seen that oil by the steam contacting partition' 13, this resulting from the fact that the compartment 13a is very shallow. Fro this Vcompartment the oil will pass through the tube 20' and be further 6 heated by the steamcontacting with .said tube and will finally. be discharged into the shallow, as heretofore stated, and the oil wil therefore be maintained in a heated condition until its v7 discharge through the pipe 16. By providing the two shallow compartments 13a and 15 the oil is not only distributed therefrom to the several tubes employed, but is also heated to a case if the oil should be discharged directly from the pipe 11 into one of the tubes 20.-.

The steam employed in the shell 14 is generally the exhaust-steam from the engine,- but may be supplied from any source, or hot air may be employed` instead of steam if 'found more convenient or advantageous.

. The pipe 11 is supplied with a controllingvalve 25.

The fuel being supplied to the burner in a 8 heated condition-vaporizcs much more rapidly than when supplied in cold condition and is therefore usedwith a greater economy and produces a materially greater heatv by Having t us describedthe invention, what is claimed as new is- In an apparatus of thecharacter described 'a fuel-heater comprising a cylindrical `shell having a steam-inlet and a steam-outlet with- 9 in opposite ortions thereof, a plate upon one end of t e shell, aplurality of tubes se- .plate and extending longitudinally within theshell, an internall screw-'threaded cap engaging one end 'of t e 1 shell and having an interior shoulder bearing upon the plate to clamp against the shell, a

' fuel-outlet extending from the center of said cap, said cap forming a shallow compartment into which one end of the tubes open, an in' I te'rnally-screw-threaded cap upon the oppo- .rateatsa march 19,1907.
